Slowly dissolving fishing lure attachment with scent mixture

Abstract

There is disclosed a fishing lure having a fish attractant body which is formed of a water soluble polymer having a slow dissolution rate. The polymer contains a fish scent attractant. The fish scent attractant can be encapsulated within the polymer, e.g., fish or blood meal can be included in the polymer so that it will be slowly dispensed into the water as the polymer dissolves. The preferred polymer is polyvinyl alcohol having a preselected degree of hydrolysis of its ester groups to achieve the desired water solubility rate, and optionally plasticized with glycerol. The attractant can be a sheet which has a plurality of parallel and coextensive slits to provide parallel strips that depend from an unslit portion thereby permitting the sheet material to be wrapped about a lure body and secured in place so that the parallel strips extend rearwardly from the body, permitting them to undulate in the water as the lure is pulled through the water simulating the swimming movements of a small fish. Other embodiments include solid form lures shaped from polyvinyl alcohol which is gelled with a soluble borate.

What is claimed is: 
     
       1. A fishing lure which comprises a body have the property of a slow dissolution rate in water and containing a fish attractant embedded within said body so that when said body dissolves in a body of water, said fish attractant is released into said water wherein said body is formed of polyvinyl alcohol having a limited rate of water dissolution. 
     
     
       2. The fishing lure of claim 1 wherein said polyvinyl alcohol includes from 0.5 to 5 weight percent glycerol to cross-link said polymer and thereby limit its water dissolution rate. 
     
     
       3. The fishing lure of claim 1 wherein said polyvinyl alcohol has from 50 to 95 percent of its ester groups hydrolyzed. 
     
     
       4. The fishing lure of claim 1 wherein said lure includes a body which supports a fish hook and wherein said attractant body is formed as a skirt which surrounds the lure body. 
     
     
       5. The fishing lures of claim 4 wherein said attractant body has a plurality of parallel slits formed a plurality of strips which are supported on said lure body. 
     
     
       6. The fishing lure of claim 5 wherein said attractant lure is formed of a sheet layer which has a plurality of coextensive and parallel slits which form said strips that extend from an unslit portion and wherein said unslit portion is wrapped about and secured to said lure body, whereby said plurality of strips extend rearwardly from said lure body and are free to move as the lure is pulled through the water. 
     
     
       7. The fishing lure of claim 1 wherein said body is molded of a solid polyvinyl alcohol polymer extended with sodium borate and containing from 0.5 to about 30 weight percent of said fish attractant. 
     
     
       8. The fishing lure of claim 7 wherein said fish attractant is fish meal. 
     
     
       9. A sheet material having a plurality of coextensive and parallel slits extending partially along it's length to form a plurality of strips which extend from an unslit portion, said sheet material being formed entirely of a polymer of polyvinyl alcohol with from 5 to 30 weight percent of a fish attractant comprising a water insoluble fish feed encapsulated with said polymer, and wherein said polymer has from 80 to 95 percent of its ester groups hydrolyzed and exhibits the property of a slow dissolution rate in water. 
     
     
       10. The sheet material of claim 9 wherein said polyvinyl alcohol is cross-linked with 0.5 to 10 weight percent glycerol. 
     
     
       11. The sheet material of claim 10 wherein said fish feed is a fish meal. 
     
     
       12. The sheet material of claim 10 wherein said fish feed is blood meal.
